     A
     The Smallest Life Around Us
     Tiny plants and animals live all around us. We cannot see them because they are so small, but they are everywhere.
     They live in the soil, the air, and in rivers and oceans. They grow on mountains and in caves. Some live in the ice at the north and south poles; some live where it is very hot. They are found throughout cities and in the country. They grow on other plants and animals. Some are even living on you, on your skin, hair, and inside your body, in your mouth, nose, and all through your intestines(肠).
     These tiny plants and animals are called microbes. The word microbe is made from two other words: micro, meaning small, and bios, meaning life. So, microbe means small life.
     Microbes have been on earth for a very long time. They may have been the first forms of life to be alive. Today there are more microbes in the world than all other living things.
     People did not know microbes had existed(存在) long. They were too small for them to see.
     But people did see many changes in their world—important changes. And they did not know what caused them. They saw food that they kept too long change color and begin to smell bad. They saw cuts and wounds grow red and painful and become infected(感染). They saw old plants and leaves and trees crumble apart on the forest floor and disappear into the soil. Such changes were a natural part of the world, but people did not understand them. They did not know these changes were evidence（证据） of tiny plants and animals growing all around them.
     31. Why couldn’t people see microbes?
     A. Because they are too small.
     B. Because they live inside our body.
     C. Because they live far from humans.
     D. Because they may have been the first forms of life to be alive.
     32. The underlined phrase “crumble apart” in the last paragraph means “______”.
     A. grow taller     B. change into soil
     C. break into tiny pieces     D. become colourful and energetic
     33. Choose the answer that completes the web below.
    
     A. Microbes are very small     B. Food begins to smell bad
     C. People can’t see microbes    D. Microbes are all around us
     B
     The place of the family computer may turn into a hot argue as your children get older. Whether you have one computer in the house or five, you should think the following things as you make a final decision.
    
     There is a certain number of danger if you allow your children to have a computer with Internet in their rooms with no parental direction. They may share improper information and chat with strangers if they know that no one will be watching.
     This does not mean that you cannot allow your children to have a computer in their rooms. Think allowing a computer without Internet. This is especially useful for teens who use the computer for creative projects, playing video games and listening to music. Keep in mind, however, that it is possible that your kids are more skilled at computers than you are and may remove any blocks you have in place.
     Computer Use
     The way your family computers are used will play a role in deciding where they should be placed. A machine used only for homework will need to be in a quiet place where there is low traffic. One used for chatting online can be in the room where most of the family spend their time. If Mom and Dad use a computer for work, those needs will also have to be thought.
     Space
     Space must also be considered in computer placement. The computer will need electricity, plenty of desk space and a spot away from this bright light of windows. You will not want it placed in a room where your kids may be noisy.
     34. The text is written for__________.
     A. parents B. teachers C. students D. children
     35. Which of the following might be a danger to children?
     A. Listening to music.     B. Doing their homework.
     C. Playing video games. D. Chatting with strangers.
     36. Which word can be put in the blank ?
     A. Safety. B. Difficulty. C. Friendship. D. Attention
     37. What can we learn from the text?
     A. A computer takes up a lot of desk space.
     B. A child should not be allowed to get online.
     C. A child should not be allowed to use a computer.
     D. Many things decide the place of family computers.
